Empire State Building, and also served as the Cult's contact to Mr. Diagoras. In the climax of "Evolution of the Daleks", Thay dismisses the warnings of the Hybrid Dalek Sec and kills him. Moments later, Thay was destroyed (along with Dalek Jast) when the Dalek Human hybrids rebelled against the orders to kill the Doctor and opened fire on the Daleks instead. According to the Doctor Who Files book on the Cult of Skaro, Dalek Thay was the Commandant of Station Alpha, the most secret Dalek research facility, before being promoted by the Dalek Emperor. Dalek Jast Dalek Jast oversaw the status of the Genesis Ark in "Doomsday". He fought in the Battle of Canary Wharf and escaped the void with his comrades. He was the fourth in command of the cult. Jast and Thay assisted Sec in experiments underneath the Empire State Building. When Sec was about to merge with Mr Diagoras and become the first Human Dalek, he and Thay intervened with Sec's experiment in order to maintain Dalek purity, but Sec retorted that their road for supremacy has brought the Daleks to extinction. Jast continued to question Sec's motives, and eventually betrayed him along with Thay and Caan. He was destroyed by the Dalek humans along with Dalek Thay by the weapons of the human Daleks. Dalek Jast had the highest-pitched voice in the Cult. He was the third member to be killed, shortly after Thay. According to the Doctor Who Files book on the Cult of Skaro, Dalek Jast was Force Leader of the Outer Rim Defensive Battalion before being promoted by the Dalek Emperor.
